MODULE 26 · 4 LESSONS

Compare the major frontend choices without turning framework collecting into a substitute for engineering judgment.

What this module changes in your work

  • Choose state by ownership, update frequency and debugging needs rather than library popularity.
  • Distinguish a CSS preprocessor, a general component toolkit and a React component system before choosing one.
  • Use local versus shared state, React Context, Redux Toolkit in one coherent implementation.
  • Complete this evidence-backed checkpoint: Rebuild one CourseFlow feature with a deliberate state boundary, then document when an alternative framework would be justified.

PROJECT CHECKPOINT

Turn frontend ecosystem and state into evidence

Rebuild one CourseFlow feature with a deliberate state boundary, then document when an alternative framework would be justified.

  • Write acceptance criteria for local versus shared state before implementation.
  • Keep the change small enough that a reviewer can connect it to the intended behavior.
  • Use the most direct check available for React Context and save the result.
  • Record one decision you would keep and one you would revisit after feedback.
